Two diagrams show the three-dimensional structure of a methane molecule: panel A uses a ball-and-stick model with a central carbon atom connected to four hydrogen atoms in a tetrahedral arrangement, while panel B illustrates the bond angle of 109.5 degrees and bond length of 1.09 angstroms between carbon and hydrogen atoms. — chemical compound Methane, in which four hydrogen atoms are bound to a single carbon atom, is an example of a basic chemical compound. The structures of chemical compounds are influenced by complex factors, such as bond angles and bond length.

To name an acid that does not contain oxygen, you use the prefix hydro- followed by the root name of the anion, ending with the suffix -ic.12

For example, when hydrogen chloride (HCl) is dissolved in water, it is named hydrochloric acid. Similarly, other common non-oxygenated acids follow this naming convention:12

HF: hydrofluoric acid12
HBr: hydrobromic acid12
HI: hydroiodic acid12
HCN: hydrocyanic acid12
H₂S: hydrosulfuric acid12

This nomenclature specifically applies to these compounds when they are dissolved in water.12
